Official forecasts for Denver on September 7 point to scattered thunderstorms and overnight lows near 61°F, placing the market's leading 64-65°F (35.5%) and 59°F-or-below (34.5%) outcomes in a near tie. Persistent moisture and cloud cover from the storm activity will limit nocturnal radiative cooling, while southerly flow advects warmer air, elevating minimum temperatures above the 52.8°F climatological average. Model spreads in boundary-layer mixing and precipitation timing create genuine uncertainty around the precise low, with traders weighing these variables against historical September variability. Updated National Weather Service guidance and local observations will refine the range ahead of market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kbkf
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
